the end of acquisition, the accuracy of the system can
be compromised. To avoid this situation, increase the
acquisition time, use a driving circuit that can settle
within t
up by setting the voltage at R/C low during the second
falling edge of CS.
For best performance, use printed circuit boards. Do
not run analog and digital lines parallel to each other,
and do not layout digital signal paths underneath the

ADC package. Use separate analog and digital ground
planes with only one point connecting the two ground
systems (analog and digital) as close to the device as
possible.
Route digital signals far away from sensitive analog and
reference inputs. If digital lines must cross analog lines,
do so at right angles to minimize coupling digital noise
onto the analog lines. If the analog and digital sections
share the same supply, isolate the digital and analog
